Or HaChaim on Genesis 19:2/אור החיים על בראשית י״ט:ב׳

1 והשכמתם והלכתם לדרככם, "and rise early and be on your way." Lot hinted to the angels that they had to hide from the local population because he was afraid that something like what happened might indeed occur, i.e. that his guests would be molested.
